Hello,

I’ve developed a cool VTK example of a stylized, animated atom structure. The example demonstrates the use of several classes, such as vtkEllipseArcSource and vtkLegendBoxActor.

I’ve looked through the official VTK examples [repository](https://gitlab.kitware.com/vtk/vtk-examples) on GitLab, but I couldn’t find a guidelines section on how to contribute. However, I found a link for developers in the src directory, but it seems to be unavailable [link](https://gitlab.kitware.com/vtk/vtk-examples/-/blob/master/Instructions/ForDevelopers).

I would appreciate any help pointing me in the right direction.

New examples are welcome. Please look at [VTK Examples](https://examples.vtk.org/site/), here, you can find the instructions in the left-hand menu in the **Instructions** section. [For Developers](https://examples.vtk.org/site/Instructions/ForDevelopers/) would be a good place to start. If you are doing a C++ example, also read the **WASM** section.

Hello,

You can also start a public repository for it in GitHub ([https://github.com/](https://github.com/)). If you’re acquainted with Git, you can share it with the world in no time.

best,

PC

@amaclean Thanks for providing the links. That’s what I was looking for.

@Paulo_Carvalho Yes, I’ve already hosted the example on a public repo ([GitHub - MujassimJamal/StylizedAtom: A Stylized Atom structure using The Visualization Toolkit (VTK) and C++.](https://github.com/MujassimJamal/StylizedAtom)) in GitHub.

Anyone is welcome to check it out. Thanks!

Thank you. That’s really a nice VTK demonstration. But, if you excuse my nitpicking, the atom model itself like a small solar system is obsolete. Electrons in an atom exist as standing waves (like those of a drum skin when we play it). Although, as you know, the accurate, probabilistic representation would be far more challenging to code.

Well, you’re right. It’s indeed very challenging to code an accurate model. Perhaps we can consider the example as a Bohr’s model? Haha.

Anyway, my main goal was to explore and use VTK classes, which I really enjoyed.
